gossip protocol port 7946

Hi

Just tried sidecar on a docker swarm cluster, but it failed because it's trying to use port 7946, the same used by swarm cluster.

Anything I can do to run both?

@njordr Thanks for trying out Sidecar! I'm not sure why we haven't exposed an environment variable to allow users to change this port. Perhaps @relistan has more insight.

In the mean time, I have created a PR (#27) to address this, which I think does what you need. Feel free to try out the gonitro/sidecar:f56be36 and set SIDECAR_BIND_PORT to some other port.

@mihaitodor thanks, your PR works like a charm :)
